A bomb detonated in a train carriage between the central Moscow metro stations Avtozavodskaya and Paveletskaya in February, 2004, and another bomb went off near the entrance to the city's Rizhskaya station in August. A total of 49 people were killed and over 300 were injured in the two terrorist attacks.
Murat Shavayev, Tamby Khubiyev and Maxim Panaryin were found guilty on charges of terrorism, murder, affiliation with a criminal group, illegal possession of arms, and the making of an explosive device.
In addition to the prison terms, the court ordered them to pay over 6 million rubles ($235,000) in damages to the families of victims and people injured in the attacks.
The three men are also suspected of involvement in a series of terrorist attacks at bus stops in the southwestern city of Voronezh and in Krasnodar, near the Black Sea.
